ABSTRACT:
Track tensioning apparatus for track-type vehicles having a track, a track frame and an idler wheel engageable with the track. The track tensioning apparatus comprises a bearing rotatably mounting the idler wheel so as to rotate about an idler wheel axis and a support for supporting the bearing to selectively pivot about a support axis parallel to and spaced from the idler wheel axis. A locking device is provided for adjustably locking the bearing with the support so that the idler wheel axis is in a predetermined angular position with respect to the support axis. In a preferred embodiment, the locking device is continuously adjustable to infinitely vary the predetermined angular position. Other locking devices are also disclosed, as well as a method for adjusting the tension of the track.
